The Reverse-Flash from the CW Arrowverse vs. The Avengers from the Marvel Cinematic Universe.
- Consists of everyone in photo, also including Vision (Latest equipment, powers and feats for all)
- They get two weeks of prep-time.
- Cannot get any outside help from S.H.I.E.L.D., Spider-Man, The Defenders, etc.
- Morals On.
- Latest and most powerful version of the character chronologically, the one Flash fought in Fast Enough.
- No prep time.
- Cannot get outside help from S.T.A.R. Labs or any allies he might have.
- Morals On (With his ruthless personality though, he's essentially bloodlusted).
New York city, downtown. They can the landscape, cars, buildings, etc to their advantage.
Who wins this fight? I personally think The Avengers take it. But Thawne could probably take down a few of them and put up a decent fight.
